Code for c programming reads and compress each row of the array by replacing each character with a single character and the number of times it occurs?
I have issue in doing this.
So I'm trying to create a function that replaces any instance of a character in a string with another. So first I tried the replace() string member function:
In my implementation file
void NewString::ReplaceChar(const char& target,const char& entry)
{
this->replace(this->begin(),this->end(), target, entry);
};
Main program
#include "NewString.h"
using namespace ...;
int main()
[Code].....
Instead of replacing the the l's with y's it outputted a long string of y's. Also, NewString is derived from the string class (it's for the assignment). the header and whole implementation file, already tested.
I've also tried, instead, to use a for loop in ReplaceChar() but I need to overload the == operator and I don't know how I should exactly:
bool NewString::operator ==(const char& target)const {
if(*this == target)
return true;
[Code]....
I want the == operator to test if the value in the char array is equal to target but I'm not sure how to pass in the position. I'm guessing the this pointer in ReplaceChar() is not the same as the one dereferenced in ==() because target is never replaced by entry in the string.
I am trying to write a function compress() that takes in an input of a 2-dimensional array (5x10) of character data, compresses each row of the array by replacing each run of character with a single character and the number of times it occurs, and prints on each line the result of compression in the function. For example, the row with data aabbcdddee may be compressed into a2b2c1d3e2.
Input (5x10 of characters):
aaacccdeee
sssseeeedd
aaaaaaaccc
eeedddasee
ddeeeeeggg
Output:
a3c3d1e3
s4e4d2
a7c3
e3d3a1s1e2
d2e5g3
I could achieve the compression part, but behind the compressed array, it printed out 5 extra lines of alien ASCI code, followed by printing out 5 times of everything .
Code:
void compress(char data[SIZE1][SIZE2])
{
int i,j, k,l ,count;
char data123;
printf("Enter your data (5x10 of characters): ");
for (i=0; i < SIZE1; i++) {
for (j=0; j < SIZE2; j++)
data[i][j] = getchar();
fflush(stdin);
}

I'm writing a function that accepts a char array containing the title of a book as parameter, the following then has to take place:
1.) Extra white spaces between words need to be removed [DONE]
2.) Text has to be converted to title case, i.e each new word has to start with a capital letter [DONE]
3.) Lastly I have I text file (minors.txt) containing a number of words that should not be capitalized by the function, like "a" and "an", however I don't know how to implement this.
Example of end product:
ENTER THE TITLE OF THE BOOK: a brief hisTOry OF everyTHING
Correct Output:
bool Book :: convertToTitleCase(char* inTitle) {
int length = strlen(inTitle);
bool thisWordCapped = false;
//Convert paramater to lower case and
//Remove multiple white spaces
for (int x = 0; x < length; x++)
[Code]...
I was thinking of maby reading the words in the text file into a string array, and then comparing the two arrays to ensure that when a word is present in a text file, the word is not capitalized, however I don't know if that is possible between a string array and a char array.
I am working on a parking lot scenario project using multidimensional arrays. The parking lot has 8 rows and 10 parking spaces in each row. Altogether there are suppose to be 30 cars parking in the lot and arrive in numerical order. I am suppose to generate a random number to represent the row and another to represent the space in the row.
The problem I have is that a few of the elements are being replaced. The project requires the car to check if the space is taken, if so it is to find another one. Here is what I have...
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define ROW 8
#define COL 10
#define CARS 30
void parkTheCars(int result[ROW][COL]);
void displayArray (int result[ROW][COL]);

This function should replace all instances of a character in a given character array, while returning the amount of characters changed, but I keep getting a segmentation fault at the highlighted area.
I'm only supposed to use pointers so arrays are out of the question, and I don't think we are allowed to use the string.h library as well. How I could avoid something the segmentation fault or ways to fix it?
Code:
int replaceChars(char replace, char find, char *input) { int i, j;
//Finds length
for(i = 0; *(input + (i + 1)) != ' '; i++);
int c = 0;
for(j = 0; j <= i; j++) {
if(*(input + j) == find) {
*(input + j) = replace; //Segmentation fault happens here
c++;
} }
return c;
}
I'm trying to right the function that puts the correct letters in the right positons being reported from my previous compareletter function for my game of hang man and its not updating the word in progress array. Here's my compare letter function that's working correctly:
Code: //function that returns the index of the letter that the user has guessed or Code: //-1 if the letter isn't in the word
int CompareLetter(char array[], char guess, int numLetters)
{
int i;
[Code....
However, this isn't changing any of the position of the asterisks in the word in progress array positions 0-3.
Can we do this :
Code:
char strings[][100]={"ABC","EFG","IJK","LKM"};
char temp[100];
temp=strings[1];
You are programming a sideways scrolling shooter. This used 2D cell based maps that are very long (over 100,000 characters per row long, 24 rows of 40 characters on screen), and the only way you can get them to fit in memory is to compress each row of the map using run length encoding and to decompress each new column of the map on the right of the screen as the background moves from right to left. You maintain a list of pointers into the RLE data for each row of the screen. Columns that are scrolled off the left are discarded. This works very well and the game only just fits in the available memory. Suddenly the game designer decides that the game should also be able to scroll from left to right at any point, and for any duration. Stunned and dismayed, you explain to him that RLE compression only works in one direction, but he’s adamant. Figure out a way of doing what he wants without using much (no more that 1K of) extra memory. Explain the algorithm used for decompressing in both directions. (assume the RLE algorithm used is: a positive byte N followed by a byte B, indicates a run of N copies of B, a negative byte -N followed by N bytes indicates that those bytes should be copied directly. For example, the sequence 2,2,2,2,5,1,2,9,9,9,9,9 would be coded 4,2, -3,5,1,2, 5,9.)
how can I compress the information? My first thought was making a change to the RLE compression but i gave up on that thinking it wasn't possible.
I've been looking for some examples of handling dropped files from within a Windows compressed folder? I suspect, ultimately I may need to identify that it is a compressed folder and extract the contents, however I have not been able to find any information about identifying the file that may have been drug out of the folder onto the form (such as the file name, zip file path etc)

View 6 Replies View RelatedThe program should store a character array in reverse order then display the reversed array. I have also included in the code that will display the actual characters into the array as it loops through. So I know the characters are being stored, but why doesn't it display the entire string when I call it?
Code:
#include<stdio.h>
int main(){

I am currently having an issue with validating user input for a state abbreviation. I have an array where a list of abbreviations is stored to use as a comparison for whatever the user inputs. I have been able to get the list loaded properly but whenever i go to compare, it always comes back as true even if it isn't. Here is some relevant code:
static char stateTable[STATE_TABLE_SIZE][STATE_SIZE];
int main() {
char buffer[40], *testCustName[40], testState[5], testCode;
buffer[0] = ' ';
int quit = 0;
int p = 0;

I have a question about an issue I am having on my final project.

I heard that const shall be preferred over #define . So I start to change my program accordingly.
But then below error message occurs during compilation:
#include "common.h"
#include "definition.h"
#include "particle.h"
int main() {
Particle *p = new Particle();
[Code] .....
I guess the error occurs because, when the line 9 of particle.h (File 4) is compiled, value of const int dimension is not seen by the compiler.

I am trying to clear the first character of my array. The first two methods don't seem to work. The third method seems to but doesn't look like a good idea.
char operand[] = "abc";

memset(operand, 0, 1);
printf("%s", operand);

Take this string for an example, "asdf 9.000 1.232 9.00 23.1 545.3"..Is there a way to replace any of the doubles with another double? Example: Replace the first "9.000" with a "10.0". I am aware that string::replace will do the trick, but how do I make it work for arbitrary cases? By arbitrary I mean that I don't know the size of the string to be replaced, I just want to be able to replace any number with a given number.
